Servings: Serves 16–20
Ingredients 1 sheet frozen puff pastry (14 ounces), thawed2 large eggs4 cups cherry tomatoes , halved3 sprigs thyme1 tablespoon olive oil1/2 teaspoon salt1/4 teaspoon freshly ground black pepper2 teaspoons anchovy paste (optional)8 ounces (1 cup) fresh goat cheese , room temperature1/2 cup whole-milk ricotta cheese1 tablespoon fresh thyme leaves , chopped1/4 cup shredded Asiago cheese
Preheat oven to 350°. Set the puff pastry on a floured work surface and cut in half crosswise. Roll out each half to a 18x16-inch rectangle. Place each rectangle on a separate baking sheet. Beat one egg in a dish.
Cut 1/2-inch strips from each edge of both rectangles. Brush a 1/2-inch border of the rectangles with the beaten egg. Place the cut strips over the egg-washed edges to form two tart shells with raised borders. Cover with plastic wrap; chill at least 30 minutes.
Meanwhile, toss the tomatoes, thyme sprigs, olive oil, salt and 1/8 teaspoon pepper in a medium bowl. Spread tomatoes on a foil-lined jelly roll pan or baking sheet. Bake 25 to 30 minutes, until tomatoes begin to shrivel and brown. Remove from oven; let cool slightly.
Brush the raised borders of the tart shells with the remaining beaten egg. Spread 1 teaspoon of the anchovy paste, if using, over the bottom of each.
Combine the goat cheese, ricotta, chopped thyme, 1 egg and 1/8 teaspoon pepper in a mixing bowl until blended. Spoon half of the mixture down the center of each pastry rectangle, spreading level and almost to the edges. Sprinkle the Asiago cheese over the ricotta mixture; top with the tomatoes, dividing evenly between the tarts.
Bake for 30 minutes, or until crust is golden. Transfer to racks to cool for 10 minutes. Cut each tart into 8 to 10 slices and serve warm.
